Metoprolol uses

Pharmacological action

Metoprolol is a cardioselective beta1-blocker without intrinsic sympathomimetic activity. This medication has antihypertensive, antianginal and antiarrhythmic effect. Metoprolol decreases automaticity of sinus node, reducing heart rate, slows AV-conduction, decreases myocardial contractility and excitability, reduces cardiac output, reduces myocardial oxygen demand. This drug inhibits the stimulatory effect of catecholamines on the heart during physical and psycho-emotional stress.

Metoprolol causes a hypotensive effect which is stabilized by the end of the second week of a course. With angina Metoprolol reduces the frequency and severity of attacks.

This medicine also normalizes the heart rate during supraventricular tachycardia and atrial fibrillation; when myocardial infarction it contributes to limit the zone of ischemia of the heart muscle and reduces the risk of developing fatal arrhythmias, reduces the risk of recurrence of myocardial infarction. When Metoprolol is used in the medium therapeutic doses it has a less pronounced effect on smooth muscles of the bronchi and peripheral arteries than non-selective beta-blockers.


After oral administration Metoprolol is rapidly and almost completely absorbed from the gastrointestinal tract, Cmax of the active substance in the blood plasma is reached after 1-2 hours. This medication intensively metabolized in the liver to form inactive metabolites. T1/2 of Metoprolol from plasma is 3-4 h and during the course of treatment it does not change. More than 95% of the dose excreted by the kidneys of which only 3% is in unchanged form.

Why is Metoprolol prescribed?

Hypertension, prevention of angina, cardiac arrhythmias, secondary prevention after myocardial infarction, cardiac hyperkinetic syndrome (including in hyperthyroidism, NDCs). Prophylaxis of migraine.

Dosage and administration

For oral administration the average dose of Metoprolol is 100 mg / day in 1-2 reception. If necessary the daily dose gradually increased up to 200 mg. For IV injections a single dose is 2.5 mg, with no effect a re-introduction is possible in 5 minutes.

Maximum daily dose for oral administration is 400 mg, for IV injections a single dose is 15-20 mg.

Antiarrhythmic and anesthetic medications increase the risk of bradycardia, arrhythmia, hypotension.

Digitalis drugs potentiate slowing AV conduction.

Simultaneously intravenous injection of verapamil and diltiazem may cause cardiac arrest.

Beta-adrenoceptor agonists, aminophylline, cocaine, estrogens, indomethacin and other NSAIDs impair antihypertensive effect.

Metoprolol enhances and prolongs the action of anti depolarizing muscle relaxants.

Combination with alcohol leads to mutual reinforcement of inhibitory effects on the CNS.

Allergens increased the risk of severe systemic allergic reactions or anaphylaxis.

Metoprolol edits the effectiveness of insulin and oral antidiabetic drugs and increases the risk of hypoglycemia.

Oral contraceptives, cimetidine, ranitidine, phenothiazines raise the level of this drug in the blood, rifampicin decreases it.

Metoprolol reduces the clearance of lidocaine, the effectiveness of beta 2-agonists (it is necessary to increase the dose of the latter).

This medicine is incompatible with MAO inhibitors of type A.

Metoprolol in case of emergency / overdose

Symptoms: hypotension, acute heart failure, bradycardia, heart block, AV block, cardiogenic shock, bronchospasm, trouble breathing and consciousness, coma, nausea, vomiting, generalized convulsions, cyanosis (manifest in 20 minutes - 2 hours after taking of Metoprolol).

Treatment: gastric lavage, the symptomatic therapy: atropine sulfate injection (IV fast 0.5-2 mg) if bradycardia and a violation of AV conduction; glucagon (1-10 mg IV, then IV infusion 2-2.5 mg / h) and dobutamine in the case of reduction of myocardial contractility; agonists (noradrenaline, adrenaline, etc.) when arterial hypotension; diazepam (IV slowly) to eliminate seizures; beta-agonists inhalation or IV jet injection of aminophylline to relieve broncho spastic reactions; cardioacceleration.
